Processor Bus Terminator
On a system with only one processor, a processor bus terminator occupies the other processor slot
on the system board. This module ensures proper termination for the processor bus; without it, the
system will not function. When you add a second processor, you must remove this module and
replace it with the new processor.
WARNING The system is always on when connected to AC power. Before performing this
task, disconnect the system’s power cord from its AC power outlet.
To remove the processor bus terminator:
Carefully pull the terminator card out of the processor slot.
